Sometimes you don’t change the amplifier itself, but what’s glowing inside it. And suddenly, the same system feels completely different. More warmth, more calm, more bite. A small component, but one with a surprisingly big impact.
Here, you’ll find audio tubes for replacement, fine-tuning, or just out of curiosity. New or used, from well-known classics to interesting finds that tube enthusiasts will instantly love.
In a tube amplifier, a large part of its character is shaped right here. Audio tubes don’t just amplify the signal; they also directly influence how music is experienced. More warmth, a different midrange, more calm, or, conversely, extra energy. Small differences on paper can feel surprisingly significant in a setup. For many hi-fi enthusiasts, replacing or swapping out tubes is therefore a logical way to further refine an existing system.
Different Types of Audio Tubes
Not every tube does the same thing. Within a tube amplifier, different types each have their own role. Here are some of the things you’ll find:
preamp tubes for signal processing and tone character
Power and speaker driver output tubes
rectifier tubes for power supply applications
replacement tubes for existing amplifiers
Specific tube types for compatible models
Which tube you need depends entirely on your amplifier. Compatibility is no minor detail here.
Why replace or compare tubes?
Tubes wear out—that’s just part of the deal. But replacing them isn’t just a matter of necessity. In fact, many enthusiasts deliberately experiment with different tubes to see how they affect their setup. Consider reasons such as:
Replace worn-out pipes
experimenting with a different tonal character
Re-optimize existing amplifiers
Search for specific or hard-to-find pipe types
Use matched sets for consistent performance
For some audio enthusiasts, this is almost a hobby in itself.
New and used audio tubes
New audio tubes offer reliability, a long service life, and a practical solution when replacement is needed. Used tubes, on the other hand, are of interest to those looking for older production runs, specific sound characteristics, or hard-to-find types. Our selection changes regularly. Sometimes we have modern productions ready to replace older ones. Sometimes something comes in that immediately piques the curiosity of tube enthusiasts. That makes this the kind of category you’ll want to check out every now and then.
What should you look for when choosing audio tubes?
The wrong tube isn’t just impractical—it might simply not work in your amplifier.Key points to note:
exact pipe type
Compatibility with your amplifier
application within the circuit
new or used
coordinated sets where appropriate
condition and expected service life
In this case, it’s always smarter to double-check than to guess.
Why browse through our audio tubes?
Because this is exactly the kind of category where curiosity and necessity come together beautifully.Sometimes you’re just looking for a direct replacement. Sometimes you’re curious to see how a different tube will affect your sound. Whether new or used, we regularly get in items that tube enthusiasts will instantly love.

CD
The Compact Disc (CD), like most inventions, did not appear out of thin air. After the invention of the laser in 1958, the first patent for optically readable disks was filed in 1961. The first digital video records were introduced in 1972. After a flop by Philips, the manufacturer, together with Sony, released the first CD in 1979. We do not know what it contained, but in 1982 the first CD was released for the market, it was the album Visitors by ABBA. In this year the first player became available and so began the elimination of the LP from the market. Many have literally thrown their LPs in the trash… we still see some visitors being disappointed when they tell us this. Velen hebben hun lp’s letterlijk bij het vuil gezet… sommige bezoekers zien wij nog steeds balen als ze dit vertellen.
Our playlist runs at full speed every day. Filled with everything, from the usual audiophile tracks to poorly recorded classics from the past, from a special Scandinavian chamber choir to hard Dutch hardcore. Enjoy it as we enjoy it too. Here are the links to the Freaklist! on Tidal, Qobuz and Spotify.
Your audio setup is your joy and life, the pride of every audio enthusiast. But your set doesn't simply evoke the same feeling from those around you. Well, it does with us! And also with many others who peek in here from time to time.
Share your setup in the Hall of Gain and let others enjoy your set.
Soon hopefully!

House rules

Live music!
Amplified or unamplified ... live music is different. You don't bring the atmosphere of a bar, club or hall into your home. And thankfully so! For those genes who sometimes leave their comfortable couches to make the exit to a concert, it might be fun to scroll through this page from time to time. Anyone who has a fun tip or wants to promote an event, please post it here especially, as well as fun clubs and bars you've discovered somewhere on the world.
Soon hopefully!
